Prevalence and risk factors of preoperative anemia in patients undergoing elective orthopedic procedures in Northwest Ethiopia: a multicenter prospective observational cohort study.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundPreoperative anemia is a common hematologic problem in major orthopedic surgery in developing countries. It is a condition in which the number and size of red blood cells are insufficient to meet the body's physiologic needs, consequently impairing the capacity of the blood to transport oxygen to the body. Preoperative anemia is common in elective orthopedic surgical patients and is an independent risk factor for perioperative morbidity and mortality. This study aimed to assess preoperative anemia prevalence and risk factors in patients undergoing elective orthopedic procedures.
methodA multicenter prospective observational cohort study was conducted from June 01 to August 30, 2022. A systematic random sampling technique was used to select the study unit. Data were collected using a structured questionnaire. Descriptive statistics were expressed in percentages and presented with tables and figures. Binary logistic regression was used to see the association between independent and dependent variables. A P-value < 0.05 was considered statistically significant.
resultPreoperative anemia's prevalence and risk factors in patients undergoing elective orthopedic procedures was 24.1[95%CI= (18.2-30.6)]. Multivariable logistic analyses showed that low monthly income level [AOR:5,95%CI:(1.36-7.98)], patient with cancer [AOR:3.4,95%CI:(3.7-8.84)], patient with malaria infectious [AOR: 3.2,95%CI:( 1.13-8.91)], patient with anti-retroviral therapy [AOR: 5.2,95%CI:( 1.8-11.04)], and previous history of surgery [AOR:1,95%CI(1.43-2.4)], were factors significantly associated with preoperative anemia.
conclusionThe prevalence of preoperative anemia among adult patients who underwent elective orthopedics procedures was high. Low Monthly income, patients with cancer, patient with malaria infection, and patients with anti-retroviral therapy, previous histories of surgery were found significantly associated with preoperative anemia. So, we recommend to health professional's early identification, diagnosis and treatment of preoperative anemia should be done to reduce the risks of anemia and related adverse outcomes.
